Because, Dammit, I’m Not Geeky Enough
My Timex Speed+Distance GPS watch seems pretty damn accurate for distance. A lot of reviewers have noticed this too. It’s also extremely consistent with itself by distance. My laps measure the same distance every day. This all makes sense because the GPS satellites it uses are accurate to thousandths of a mile.
I have punched numbers into my handy Excel running log thingy however and found that it consistently underestimates my speed by about 0.1 km/h. I think this is because of the algorithm it uses to compute my speed. I don’t think that it’s averaging all the readings in total because it doesn’t have the memory for that. I bet it’s doing some sort of moving averages calculation.
My name is Rusty, and I’m an unapologetic geek that somehow started running. May God have mercy on all of you.
